HPE 845972-B21 100Gb QSFP28 Bidirectional Transceiver

**HPE 845972-B21 100Gb QSFP28 BiDi Transceiver Summary:**

This HPE-branded transceiver enables high-performance 100Gbps data transmission over **a single standard single-mode fiber strand** (Duplex LC, SMF). Its core innovation is **bidirectional (BiDi)** technology, transmitting and receiving different wavelengths (1270nm/1330nm) on one fiber. Key features include:

* **100Gb/s Speed:** Delivers high-bandwidth connectivity.
* **Single Fiber Strand:** **Reduces fiber infrastructure costs and complexity** by halving the required fiber pairs compared to standard 100G transceivers.
* **1km Reach:** Suitable for campus/data center interconnects.
* **Genuine HPE:** Ensures full compatibility, warranty, and support in HPE systems.
* **Hot-pluggable QSFP28:** Easy deployment and maintenance.
* **Digital Diagnostics:** Simplifies monitoring and troubleshooting.

**Primary Benefits:** Maximizes existing fiber capacity (effectively doubling it), lowers cabling costs, simplifies network design, and guarantees reliable performance within HPE environments. **The unique selling point is achieving 100G speeds using only one fiber strand via bidirectional technology.**
